%X Friction and wear properties of steel against aluminum were evaluated on a ring-on-block tribotester.The tests were carried out under lubrication of liquid paraffin(LP) alone and liquid paraffin containing oleic acid surface-modified Cu nanoparticles.Effects of concentration and load on the tribological properties of Cu nanoparticles were investigated.LP containing 0.25% Cu nanoparticles exhibited the best tribological properties and good wear resistance and friction reduction at different loads,especially at applied loads between 50 N and 125 N.Thin copper film formed and spread out on metal surface,which provided low shear strength,prevented transfer of Al to steel surface and reduced friction and wear.
